pca

说明：  m-map工具箱，可以帮助画图，比如世界地图的背景(M-map toolbox, can help draw pictures, such as the background of the world map)

本次变成是基于matlab的有关图像压缩的仿真程序，希望能帮到大家(This is a simulation program of image compression based on MATLAB. I hope to help you.)

对图形进行二维傅里叶变化后的频谱进行中心化(Centralization of the spectrum after two-dimensional Fourier transform)

说明：  脉冲压缩技术是匹配滤波理论和相关接收理论的一个很好的实际应用。它的提出很好的解决了这样的一个问题：在发射端发射大时宽、带宽信号，以提高信号的速度测量精度和速度分辨力，而在接收端，将宽脉冲信号压缩为窄脉冲，以提高雷达对目标的距离分辨精度和距离分辨力(Pulse compression technology is a good practical application of matched filtering theory and related receiving theory. It solves such a problem very well: transmitting large time-width and bandwidth signals at the transmitter to improve the speed measurement accuracy and speed resolution of the signal, and compressing the wide pulse signal into narrow pulse at the receiver to improve the range resolution accuracy and range resolution of radar to target.)

很好的图像分割软件，内有全部源码，对研究matlab图像识别处理很有帮助(good image segmentation software, comprising all the source code, the study Matlab image recognition processing helpful)

数字信号处理或图像处理常用工具箱matlab(Common toolbox for digital signal processing)

any help to perform DCT IDCT walsh inverse walsh on image

利用SFS算法实现3D图像重建，附带有图片实现(3D Image Reconstruction Using SFS Algorithms)

说明：  图像分块的处理和matlab水印的提取，(Image sub-block processing and matlab watermark extraction,)

过线检测：依据物体运运动轨迹，分析是否过线 (In lane detection: Based on the trajectories of objects transported to analyze whether the line)
